一株产蓝色素菌株的筛选及初步鉴定

Isolation and preliminary identification of strains producing blue pigment

摘要: 从自贡地区土壤中分离得到一株产蓝色素细菌,编号为T2013。通过形态特征观察、生理生化实验分析和全细胞脂肪酸检测以及16S r DNA比对分析,确定了该细菌为杜擀氏菌属的一种。通过系统进化树显示该细菌与菌株Duganella nigrescens strain YIM H16(EF584756)具有较高的同源性。T2013可能为新种,命名为Duganella sp.T2013。

Abstract: A bacteria T2013 producing blue pigment was isolated from the soil in Zigong.According to morphological observation,biochemical and physiological characteristics experiment,whole- cell fatty acid detection and16 S r DNA sequence alignment,the strain was identified as one strain of the genus Duganella sp.. Phylogenetic analysis showed that strain T2013 had high homology with Duganella nigrescens strain YIM H16( EF584756).This strain isolated was likely to be a new member of the Duganella sp.,tentatively named Duganella sp.T2013.
